Why do two electric field lines not intersect each other ?
Figure shows electric field lines due to a charge configuration, from this we conclude that
A metallic sphere is kept in between two oppositely charged plates. The most appropriate representation of the field lines is
A charge $'q'$ is placed at one corner of a cube as shown in figure. The flux of electrostatic field $\overrightarrow{ E }$ through the shaded area is ...... .
Gauss’s law is true only if force due to a charge varies as
If the electric flux entering and leaving an enclosed surface respectively is ${\varphi _1}$ and ${\varphi _2}$ the electric charge inside the surface will be
